The remote host is affected by the vulnerability described in GLSA-200905-05 (FreeType: Multiple vulnerabilities)

Tavis Ormandy reported multiple integer overflows in the     cff_charset_compute_cids() function in cff/cffload.c, sfnt/tccmap.c and     the ft_smooth_render_generic() function in smooth/ftsmooth.c, possibly     leading to heap or stack-based buffer overflows.

Impact :

A remote attacker could entice a user or automated system to open a     specially crafted font file, possibly resulting in the execution of     arbitrary code with the privileges of the user running the application,     or a Denial of Service.

Workaround :

There is no known workaround at this time.
